I had one of the big roots in my seed producing bed, the top got hung up under the leaves/mulch and it actually broke it's stem a bit before the rest got out. It did make it all out but the main stem is damaged. It was still hanging in there last time I looked. Not sure if it will make berries or not this year.
Those 3 prongs you pictured - looking good, what year are they in ? Is this their 2, 3, or 4th spring ?
They don't look like 2 year olds to me, more like 3 or 4.
